The cigarette lighter socket can be used for
accessories with a maximum power consump-
tion of 180 W

(15 A).
If you use the sockets to connect accessories
for long periods when the engine is switched
off, the starter battery may discharge. An
emergency cut-off ensures that the on-board
voltage does not drop too low. If the on-board
voltage is too low, power to the socket is auto-
matically cut. This ensures that there is suffi-
cient power to start the engine. 12 V socket
When the key is turned to position 1 in the
ignition lock, the sockets can be used for accessories with a maximum power consump-
tion of

180 W (15 A).
If you use the sockets for long periods when
the engine is switched off, the starter battery
may discharge. If the on-board voltage is too
low, it might then no longer be possible to
start the engine.
The socket in the center console and the
socket in the side of the cargo compartment
are not automatically deactivated if the on-
board voltage is low. The additional sockets in
the rear compartment are automatically deac-
tivated if the on-board voltage is low.
Additional 12 V sockets may be located in the
rear corner trim next to the tailgate and in the
side trim on the left and right-hand sides.

WARNING
If you operate information and communica-
tion devices while driving, you may be dis-
tracted from the traffic conditions. You
could even lose control of the vehicle. There
is a risk of an accident.
Only operate these devices when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are currently driving when operat-
ing mobile communication equipment.
Please remember, a navigation system does
not supply information on the load-bearing
capacity of bridges or the overhead clearance
of underpasses. The driver remains responsi-
ble for safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By
using an exterior antenna, a possible health
risk caused by electromagnetic fields, as dis-
cussed in scientific circles, is taken into
account. Only have the exterior antenna instal-
led by a qualified specialist workshop.
Failure to observe the Mercedes-Benz installa-
tion specifications can result in the invalida-
tion of your vehicle's operating permit.
You will find information on retrofitting electri-
cal or electronic equipment under “Vehicle
electronics” (Y page

Stowing and features Z

replaced. If you use load securing aids or tie
downs which are worn out, the load may not
be sufficiently secured and could cause dam-
age to property.
In the event of an accident, have a damaged
cargo compartment floor or loading area, the
cargo tie-down rings and the tie down checked
at a specialist workshop. Otherwise, the load
may not be correctly secured the next time
anything is stowed.
Even if you follow all loading guidelines, the
load increases the risk of injury in the event of
an accident. Observe the information in the
"Securing a load"
(Y page 244) and "Load dis-
tribution" (Y page 243) sections.
You will find information about the maximum
roof load under "Cargo tie-down points and
carrier systems" (Y page 313). You will find
information about roof carriers under "Carrier
systems" (Y page 249). Before loading
! The anti-slip mats cannot be used for
securing goods and must be replaced when
they show signs of:
R Permanent deformation and crushing
R Crack formation
R Cuts
X Tire pressure: check the tire pressure and
correct if necessary
(Y page 282).
X Cargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to
prevent the load from slipping.
X Place non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary. During loading
X Observe the gross axle weight rating and
permissible gross vehicle weight for your
vehicle.
Take into account that your vehicle's curb
weight is increased if accessories or optional equipment are installed. The maxi-
mum payload is thus reduced.
X Observe the notes on load distribution
(Y page

243).
The overall center of gravity of the load
should always be as low as possible, cen-
tered and between the axles near the rear
axle.
X Secure the load (Y page
244).
Observe the legal requirements of the coun-
try in which you are currently driving. Checks after loading
G
DANGER
Combustion engines emit poisonous
exhaust gases, such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the tailgate/rear-end door is open when
the engine is running, especially if the vehi-
cle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate/rear-end door. Never drive the
vehicle when the tailgate/rear-end door is
open.
X Securing luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during
a long journey, and correct it if necessary.
X Doors/tailgate: close the sliding doors and
tailgate/door.
X Tire pressure: adjust the tire pressure
according to the vehicle load
(Y page 282).
X Driving style: adapt your driving style
according to the vehicle load. Load distribution
General notes
! Excessive loads on individual points of the
cargo floor or on the load surface impair
vehicle handling characteristics and could
cause damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle. Load distribution

WARNING
When you load the roof, the center of gravity
of the vehicle rises and the usual driving
characteristics, as well as steering and brak-
ing, change. The vehicle tilts more severely
when cornering and may react more slug-
gishly to steering input.
If you exceed the maximum roof load, the
driving characteristics, as well as the steer- ing and braking, will be greatly impaired.
There is a risk of an accident.
Adjust your driving style and never exceed
the maximum roof load.
You will find information about the maximum
roof load under "Cargo tie-down points and
carrier systems"
(Y page 313).
! Make sure that:
R the screws of the roof carrier are tight-
ened to a maximum torque of 7.4 lb-ft
(10 Nm) in the threaded holes provided
and
R there is a minimum bolt penetration of
4 turns.
Only install roof carriers and rear racks that
have been approved or recommended for
Mercedes-Benz vehicles. This will help avoid
damage to the vehicle.
You can install a roof carrier on the roof and,
for example, a rear-mounted cycle rack on the
tailgate.
Install the protective caps on the securing
threads after you have removed the roof car-
rier.
If you have installed a rear rack on the tailgate,
the additional weight reduces the assistance
provided by the gas pressure springs when the
tailgate is opened. You will then need more
force to open the tailgate. At low outside tem-
peratures below freezing you will need to pro-
vide extra support for the tailgate to prevent it
from sinking unintentionally. Carrier systems
